We all complain. Some do little, some do too much of it. Some about everything and some about specific aspects that they dislike.
When you complain’s constantly just because you can (and one thinks that it is their God given right) , it can get annoying for others and frustrating for you as they never seem to go anywhere. Don’t blame if others start completely ignoring you and your complains!
But complaints get more attention when they are meant to lead to improvement, both for you and other parties involved. What I call win-win situation! Part of your complain should also include message on how resolving it will benefit the other party and many other people like you and provide a long lasting effect.
